UNITED STATES PATENT OFFICE.

GEORGE E. ADAMS, OF PROVIDENCE, RHODE ISLAND.

SUSPENDER CAST-OFF.

SPECIFICATION forming part of Letters Patent No. 487,690, dated December 6, 1892.

Application filed August 24, 1892. Serial No. 443,991. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. ADAMS, of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Clasps; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in clasps which are particularly adapted for use on suspender-buckles,but which may be used in a variety of ways on difierent articles.

The object of the invention is to produce a spring-clasp which will be simple in construc-. tion and operation.

The further object ofthe invention is to produce a spring-clasp which is particularly adapted to serve as the swiveled cast-off of a Suspender-buckle.

The invention consists in the peculiar construction of the two parts forming the clasp, in which the annular grooved or concave flange of one portion is engaged in a perforation in the other part, of which a section of the edge is separated to form a spring-arm, together with other novel features of construction and combination of parts, which will hereinafter be more clearly described, and pointed out in the claims.

Figurel represents a front view of a buckle of which the improved clasp forms the castoff. Fig.' 2 represents a vertical sectional View of the same, indicating the operation of the parts when being separated. Fig. 3 represents a front view of the base or back plate extended to form the clamping-plate of a buckle, showing the spriug-ar1n.

Similar numerals of reference designate corresponding parts throughout.

In carrying out my invention I take a front plate 5, which may be of any desired shape and is provided with suitable means for securing it to the material, that shown in the drawings being furnished with a depending loop. In the center of this plate I now form the perforation 6, the metal bent backward to form this perforation being bent to form the concaved annular flange 7, or the flange may be formed of a separate piece of metal and then secured in any desired manner to the back of the plate 5. This flange 7 has an inwardly-turned edge 8 to guide it into the perforation of the back plate.

In the center of the back or base plate 9 I form a perforation 10, and from the metal surrounding this perforation I stamp or cut an arm 11, which may be stiffened in any suit-'6c able manner to give resilience to the same.

The operation of the clasp is extremely simple and will be readily understood by reference to Fig. 2 of the drawings. The lower portion of the front plate 5 is bent backward over the lower edge of the back plate. The spring tongue or arm ll will be bent outward until released from the concavity in the flange 7, when it will fly back into place. In securing the parts of the clasp together the upper portion of the concave rim is first engaged with the end of the spring-tongue, a slight pressure then being sufficient to spring the tongue enough to allow the flange 7 to pass through the perforation 10 of the back plate.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.

1. A two-part clasp consisting of a front plate having an annularnconcaved flange and a back plate having a circular perforation to receive said flange and a spring-tongue extending slightly into the perforation to engage the concavityof the flange, as described.

2. The combination, with the front plate 5,

having the annular concave flange 7, of the back plate 9, having the perforation 10 and the spring-tongue 11, as described.

3. The combination, with the clampingplate of a buckle having the perforation 10 c GEORGE E. ADAMS.
